Check the database size from SQL Enterprise Manager->Select the database, right click and select properties and find the size. Check the size from CET ClusterDependentConfig and the Serviceability tool. The size should be same in all the places. This size should be same in both the nodes as well.

Recommended Action

If there is a size mismatch between the actual size and the CET->Cluster Dependent Config entry, correct the size same as in node1 using node2 CET and restart Node Manager in both the nodes. Do node2 component activation again.
